COMBINATION COOKING-RANGE.

Specification of Letters Patent.

Patented June 26, 1917;

Application filed April 13, 1916. Serial No. 90,882.

To all whom it may concern:

Be it known that I, WILLIAM F. SPIETH, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a' certain new and useful Improvement in Combination Cooking-Ranges, of which the following is a full, clear, and exact description.

The object of this invention is to provide a cheap and efficient cooking range which can burn either coal or gas as fuel.

The invention consists in the construction and combination of parts shown in the drawing and hereinafter described and definitely pointed out in the appended claims.

In the drawing, Figure 1 is a perspective view of a cooking range which embodies the invention,the oven door being omitted. Fig. 2 is a top plan view, with the rear part sectloned in the plane of line 2-2 on Fig.-

3. Fig. 3 is a sectional front view in the plane of line 3-3 on Fig. 2. Fig. 4: is a sectional end view in the plane of line H on Fig. 2. Fig. 5 is an enlarged vertical section through the left burner box and adjacent part of the end of the stove, and Fig. 6 is a left end view of the front part of the left burner box, when the outer plate thereof has been removed.

The stove which is shown in the drawing, and in which theinvention is embodied, is of familiar construction in so far as concerns those characteristics of construction which adapt it to burn coal and utilize the resultant heat for cooking purposes. contains in one end (the left end) a coal burning fire pot 10. It likewise contains an oven 12 which is spaced away from the top 14, the right end 16, andthe bottom 17 of the stove, so as to form within the stove. and around the oven, the top oven flue 20, the

end oven flue 21, and the bottom oven flue,

22,which flues are serially in opencommunication with one another. ,'The left end of the oven serves as the inner wall of the fire pot. This wall should not extend much if any above the top of the oven; wherefore the fire pot is in open communication with the top oven flue. On the rear side of the stove is a smoke box 23. The bottom oven flue 22 communicates with this smoke box through a suitable opening 24 in the rear wall of the stove- ,The top oven flue 20 also communicates with the smoke box through an opening 25 in the rear all of the steveg an a damper 26 is provided for closing this opening when desired.

In order that the above described coal burning cooking range may be adapted to burn gas, and to perform all of the functions which it can perform when coal'is burned, but in a more economical and satisfactory manner, two burner boxes 30 and 40 are respectively secured to opposite ends ofthe stove just below the top thereof; and these burner boxes communicate with the interior of the stove. through long narrow horizontal slots 18 16 in the ends of the stove,-each of which slots is provided with a damper. Each of these burner boxes is preferably open at its bottom; and it contains a pipe burner, that is, a pipe having rows of jet openings; and each burner is of course, associated with means for supplying gas thereto as desired.

The specific construction shown in the drawing for' producing the combination stove, above referred to in general terms,-is as follows: Each burner box comprises an inner wall 31, two end walls 32, a top 33, and a removable outer wall 34; but it has no bottom. A slot 35 is formed in the inner wall 31, and this is surroundedby a marginal flange 36 which is passed through and fits the adjacent slot 18 16, above referred to, formed in that end wall of the stove to which the burner box is secured by suitable means. The inner surface of the lower wall of this flanged slot 35 is beveled or curved as shown at 37. Within the box a damper 50 is pivoted, said damper being adapted to cover or uncover the slot 35 as required.

A horizontal pipe burner 52 is arranged in the burner box just below the slot 35;

and in this pipe burner are two rows of jet holes 53 disposed at such angle that they will discharge directly into the adjacent slot 35.

To support the pipe burner two ring brackets 38 are formed on theinside face of the wall 31. The pipe burner 52 goes through these ring brackets, and is fixed therein with the jet holes at the proper in clination, by set screws 39.

The burner in the burner box that is fixed to the left end of the stove contains an internal cross partition 54 which in effect makes two burners out of this pipe. The front burner is supplied with gas through a valve controlled gas pipe 55; and the rear burner is independently supplied with gas its from the valve controlled gas pipe 56. The burner in the burner box at the right end of the stove is independently supplied with gas through the valve controlled gas pipe 57.

It will be readily understood that if one Wishes to burn coal in this stove he may do so by keeping both of the dampers 5O closed. If, however, he Wishes. to use gas as fuel, and wishes to be able to heat cooking utensils placed anywhere on the top of the stove, and wishes at the same time to bake in the oven, he will close the damper 26, will close the damper in the right burner box, and will open the damper in the left burner box, and will light both of the burners in said left burner box. The result will be that a wide sheet of flame will sweep out of the burner box through the flanged slot thereof into the stove, and will fiow beneath the entire top of the stove through the open flue 20, then down in the oven flue 21, and under the oven in fiue 22, and into the smoke box through the opening 24.

If one wishes merely to bake and not to cook on the top of the stove, he will close the damper in the left burner box and open the damper in the right burner box and light the burner therein. A sheet of flame will pass out of the burner box through the flanged slot therein into the stove, and thence down the oven flue 21 into the oven flue 22 and into the smoke box through the opening 24. If he wishes to cook at all points on the top of the stove, but does not wish to heat the oven, he will open the damper 26 and the dampers in both .burner boxes, and light the burners in said burner boxes. If he desires to heat only a part of the stove top for the purpose of cooking thereon, he may accomplish this in various ways. To heat the two left rear stove covers he will light the rear burner in the left oven box, will open the damper of said burner box, and will open the damper 26, and close the damper in the right burner box. To heat the two right stove holes and the two middle stove holes one may light the burner in the right hand burner box and open the damper thereof and close the damper of the 'left hand burner box, leaving the damper 26 isfactory employment of the stove, but it is.

of considerable advantage in the summer time when one only Wants to heatthe stove to do some particular bit of cooking and wantsto avoid having the stove heated to a degree as will heat the kitchen.
